Polymorphic microsatellite loci in Polemonium brandegei and P. viscosum (section Melliosoma , Polemoniaceae) 1

• Premise of the study : Microsatellite markers were isolated in Polemonium brandegei and P. viscosum to be used in future studies of mating system evolution, population structure, and hybridization. • Methods and Results : Six loci were used in a preliminary genetic diversity study in two populations each of the closely related Polemonium brandegei and P. viscosum . We found 39 alleles across the six loci (average 7 per locus), with overall levels of observed heterozygosities ranging from 0.067 to 0.867 in P. brandegei and 0.000 to 0.666 in P. viscosum . Additional primers are reported, but require further design and optimization. • Conclusions : The reported markers will aid in further studies of mating system evolution, population structure, and hybridization in P. brandegei and P. viscosum .
